  "abstract": "The Slicer Combined with an Array of Lenslets for Exoplanet Spectroscopy (SCALES) instrument is a 1-5 micron imager and 2-5 micron integral field spectrograph, currently being commissioned on the Keck II Telescope. SCALES is optimized for exoplanet high-contrast imaging and spectroscopic characterization, and will be sensitive to older, colder exoplanets than existing instrumentation. The 12.3\" x 12.3\" imaging channel is designed to replicate the capabilities of NIRC2, and the low (R~35-200, 2.2\" x 2.2\" FOV) and medium (R~2500-5000, 0.36\" x 0.34\" FOV) spectral resolution modes offer new capabilities compared to existing Keck instrumentation. We present preliminary optical performance results from laboratory testing and commissioning of SCALES.",
